GAS-WASHBOX.

Specication of Letters Patent. Patented May 28, 1918.

Application led January 8, 1916. Serial No. 70,924.

To all whom t may concern.'

Be it known that I, CHARLES S. CHRIS- MAN, a citizen of the United States, and a resident of West Chester, in the county of Chester and State of Pennsylvania, have invented certain new and' useful Improvements in Gas-lVashboxes, of which the following is a speciication.

The principal objects of the present invention are to avoid vibratory action in the wash box and prevent such leakage as is caused thereby; to reduce the backressure on the gas machine connected with t e wash box and so permit of the reduction in Weight of the stack valves; to avoid agitation of water in the Wash box and consequently permit of the use of less water, and to accomplish the above objects without increasing the size of the wash box.

The invention will be claimed at the end hereof, but will be first described in connection with the embodiment of the inven tion chosen from others as being the best now known to me for illustration in the accompanying drawings, in which- Figure l, is a sectional view of a wash bo embodying features of the invention, an

Figs. 2, 3, 4, and 5 are respectivelyr a top view, a side elevation, a vertical section, and

- a bottom view of a dip element embodying features of the invention and shown in Fig. 1 upon a reduced scale.

In the drawings 1 is a dip element for a gas wash box 2, and it comprises a hollow body having at one end a circular gas inlet opening 3 and having at the other end projecting continuous parallel walls 4, 5, 6, and 7, inclosing quadrant shaped gas openings 8 commensurate in area with the gas inlet opening 3, and forming between them a cruciform rentrance space 9 and providing in the aggregate an extensive rim wall in respect to the combined areas of the outlets 8. Of course the number of the outlet openings S and the shape thereof, as well as the shape of the inlet opening 3, may be varied while still retaining the benefit and use of the invention, but as described the device has certain structural advantages that will be appreciated by those skilled in the art.

The arrow 10 and connection 11 indicate that gas is delivered through the outlets 8 as from a point beneath the stack valve of a superheater of a water gas set, which is not shown but is well understood. The wash box is provided with an oiftake 12 which generally communicates with a gas-trunk oiftake 13. 14 are water inlet and 15 are water outlet connections for the wash box in which the level of water is maintained at an appropriate distance above the lower end of the dip element.

It has been said that the projecting walls 4, 5, 6 and 7 provide in the aggregate an extensive rim wall in respect to the combined areas of the as outlets 8. This means that the relation zbetween the area of the wash box and the area of the openings 8, which is usually adopted can be preserved while at the same time the rim over which gas passes is so long that the gas can freely escape into the wash box, thus the formation of bubbles which upon breaking produce a deleterious vibratory eife'ct in the wash box are avoided. Again by reason of the great length of the rim the back pressure is reduced and in consequence the pressure in the gas machine is reduced and the stack valve can be lighter. It is customary to connect several gas machines to the trunk 13, so that when some of these machines are making gas the wash box of another machine which is not making gas is exposed to the pressure of the gas made by the iirst machine and it is in this connection that it is important to preserve the established ratio between the area of the wash box and the combined areas of the outlets 8, so that gas may not pass backward through the seal.

It will be obvious to those skilled in the art to which the invention relates that modiications may be made in details of construction and arrangement without departing from the spirit of the invention, hence the latter is not limited otherwise than the prior state of the art and the appended claims may require.

What I claim is:

1. A dip-element for a gas wash-box comprising a hollow body having at one end a circular gas-inlet-opening and having at the other end projecting continuous walls parallel with the central axis of the body and respectively inclosing quadrantshaped gas outlet openings commensurate in area With the gas inlet opening and forming between them a cruciform rentrant space, and providing in the aggregate an extensive rim Wall in respect to the combined areas of the gas outlets. Y

2. A clip-element for a Washbox compris ing a hollow body having at one end a gas inlet opening and having at the other end projecting continuous Walls parallel With the central axis of the body and respecn tively inclosing gas outlety openings and forming bet-Ween them re'e'ntrant space and providing in the aggregate an extensive rim Wall in respect to the combined areas of the gas outlets.

3. A dip-element for a gas Wash-box oou prising a hollowy body having at one end a gas-inlet-opening and having at the other end projecting continuous Walls parallel With the central axis of the body and respectively inclosing sector-shaped gas outlet openings commensurate in total area with the gas inlet opening and forming between them rentrant gas discharging spaces, and thus providing in the aggregate an extensive rim Wall in respect to the combined areas of the gas outlets.
